The list of what is broken in the old driver for 372N/302N is rather large as they are actually very different to the other chips. I've got the correct timing tables and PLL tune information for the 302N now which appears to be very similar if not identical for these needs so if someone wants to hack the old drivers/ide/pci driver a bit I can provide reasonably accurate chip id and chip pll base information to enable a fix. PS: Anyone got a 371N (specifically 371N) can send me the pci id and rev. ^ permalink raw reply [flat|nested] 6+ messages in thread

I'm currently working on the old driver to bring in the HPT371N support and fix HPT371 clock setup (and make the other chip's clock setups correct along the way). Unfortunately I can test only on 371N and 370A, the board with 371 soldered in has PCI contreoller fried. WBR, Sergei ^ permalink raw reply [flat|nested] 6+ messages in thread

The driver rewrite is almost complete (after being preempted several times), I'm awaiting it to also be tested on HPT302. The changes are HUGE, the patch is about 70 KB in size... Meanwhile, I've noticed (just now :-) a bug in HPT372N clock turnaround code (it accesses extra DMA ports relative to dma_base, not dma_master which would make it do BAD things if called on a secondary channel) -- guess I should post them in a separate patch?

I have them queued to review in depth, although in that specific case I don't know if I can help - none of my cards set the BIOS provided value.. ^ permalink raw reply [flat|nested] 6+ messages in thread

Judging on a FREQ value (about 125) from the boot logs, the BIOS had set up PLL to 50 MHz (125/192 ~ 32/50) which should have "spoilt" the value in the f_CNT register. Hence, we may guess that the BIOS had saved the f_CNT value beforehand. If not, there's not much we can do except to guess at the DPLL frequence that BIOS might have set.
